PUMP GP-WATER 2W8001 - Caterpillar

Caterpillar Extended Life Coolant (ELC) does not require frequent additions of Supplemental Coolant Additive (SCA). Only add any SCA after an addition is determined from the results with an SCA test kit.Check the cooling system after the engine is stopped and after the engine is cool.
Loosen the cooling system filler cap slowly in order to relieve pressure. Remove the cooling system filler cap.
Drain enough coolant from the cooling system in order to allow enough room for the addition of this Extender.
Add Extender according to the requirements for your engine's cooling system capacity. Note: Refer to the Operation and Maintenance Manual, "Refill Capacities" in the Maintenance Section for the capacity of the cooling system for your engine. Refer to the Operation and Maintenance Manual, "Cooling System Specifications" information for the Caterpillar ELC Extender additions.
Clean the cooling system filler cap, and inspect the cooling system filler cap's gaskets. Replace the cooling system filler cap if these gaskets are damaged.
Reinstall the cooling system filler cap. Replace the SCA Element (If Equipped)

(1) Inlet valve. (2) Outlet valve. (3) SCA element.
Close inlet valve (1) for the SCA maintenance element, and close the outlet valve (2) as well.
Remove the SCA element (3). Remember to properly discard the SCA element.
Clean the SCA element's mounting base, and make sure that the old gasket is removed.
Coat the gasket for the new SCA element (3) with coolant. Note: Refer to Operation and Maintenance, "Cooling System Specifications" for the proper SCA element for your system.
Place the element into position. Tighten the SCA element until the seal contacts the base. Tighten the SCA element (3) by another three quarters of a turn by hand. Do not overtighten the SCA element.
Open inlet valve (1) and open outlet valve (2).
Remove the cooling system filler cap, and start the engine in order to check for leaks. Allow the coolant level to stabilize.
Add the necessary amount of coolant/water mixture in order to increase the coolant level to the proper level. The proper level for the coolant/water mixture is an amount that is at 13 mm (0.5 inch) below the bottom of the pipe. If equipped, use a sight glass to make sure that an appropriate amount of coolant/water mixture is added.
Clean the cooling system filler cap, and inspect the filler cap's gaskets. Replace any damaged gasket. Also, clean the receptacle for the cooling system filler cap. Finally, install the cooling system filler cap.
